Reloading .45 ACP R-P Brass (Remington-Peters)

A question on reloading .45 ACP Remington R-P brass:

I separated all the different headstamp brands of my brass. They all seem about the same running through the press until I started on a batch of Remington R-P. Using a Lee Classic Turret press during the bullet seating process on the R-P casings, the bullet felt like it went In to easy without very much tension. The factory crimp die feels like it barely touches the casing. I'm concerned about setback when the round is chambered.

Is this the norm with Remington-Peters brass and should I have any concern using this once shot (by me) brass? I feel like tossing it but I have about 300 pieces of R-P brass and about the same in unfired Remington UMC

I had a batch of Rem .45 ACP that simply would not hold proper tension with two different sets of dies. Set back WAS problem, I have not used Rem .45 cases since.

I really don't feel comfortable at all using this Remington brass especially since I'm at the beginner stage of reloading. Instead of tossing them I'll just put them back encase someone else may want them.

I've loaded about ten rounds with the R-P brass. Like I said In the OP the Lee factory crimp die just slips over the case with hardly any friction. If I ran down the crimp die 1/2 to a full turn will I get more bite on the crimp? It's the setback during the chambering that concerns me.

E.T.A.: If I get a OAL reading then chamber the round a couple times and there is no deviation on the OAL... would this be a sufficient way to check for setback?

I give the final rounds a squeeze between my thumb and side of pointer finger to check for setback, if I feel the bullet sink down into case, I pull the bullet. I load .40 and had issues with RP nickel and JHP not staying at my OAL 1.125. Pulled them and loaded them with plated FP with no issues at all. I had tried to increase crimp on those and went a tad too far and wrinkled the bottom of a few cases. The bullets I pulled had a nice line of crimp around them. I just thought the JHP is a harder jacket and with thin RP nickel cases, it was a bad mix for setback.
